What are the three elements of the fire triangle?

• A. Oxygen, Water, and Heat
• B. Fuel, Oxygen, and Heat
• C. Smoke, Air, and Heat
• D. Water, Fuel, and Oxygen

Answer: (B)

The fire triangle is defined by three elements that must be present for a fire to start and keep burning: fuel to feed the flame, heat to maintain ignition, and oxygen to sustain combustion. If any one of these is removed, the fire goes out. The best answer lists fuel, oxygen, and heat, matching these fundamental factors exactly. Water isn’t one of the elements; it’s a cooling agent that removes heat and can help extinguish a fire, not a structural part of the fire triangle. Smoke is a byproduct, and while air contains oxygen, the essential element is oxygen itself, so listing air isn’t the same as listing the required component. The other option that includes water is also incorrect for that reason.
